<p><code><span data-if="hdevelop" style="display:inline">class_2dim_unsup</span><span data-if="c" style="display:none">class_2dim_unsup</span><span data-if="cpp" style="display:none">Class2dimUnsup</span><span data-if="com" style="display:none">Class2dimUnsup</span><span data-if="dotnet" style="display:none">Class2dimUnsup</span><span data-if="python" style="display:none">class_2dim_unsup</span></code> performs a classification with two
single-channel images.  First, a two-dimensional histogram of the two
images is computed (<a href="histo_2dim.html"><code><span data-if="hdevelop" style="display:inline">histo_2dim</span><span data-if="c" style="display:none">histo_2dim</span><span data-if="cpp" style="display:none">Histo2dim</span><span data-if="com" style="display:none">Histo2dim</span><span data-if="dotnet" style="display:none">Histo2dim</span><span data-if="python" style="display:none">histo_2dim</span></code></a>).  In this histogram,
the first maximum is extracted; it serves as the first cluster
center.  The histogram is computed with the intersection of the
domains of both images (see <a href="reduce_domain.html"><code><span data-if="hdevelop" style="display:inline">reduce_domain</span><span data-if="c" style="display:none">reduce_domain</span><span data-if="cpp" style="display:none">ReduceDomain</span><span data-if="com" style="display:none">ReduceDomain</span><span data-if="dotnet" style="display:none">ReduceDomain</span><span data-if="python" style="display:none">reduce_domain</span></code></a>).  After this,
all pixels in the images that are at most <a href="#Threshold"><i><code><span data-if="hdevelop" style="display:inline">Threshold</span><span data-if="c" style="display:none">Threshold</span><span data-if="cpp" style="display:none">Threshold</span><span data-if="com" style="display:none">Threshold</span><span data-if="dotnet" style="display:none">threshold</span><span data-if="python" style="display:none">threshold</span></code></i></a>
pixels from the cluster center in the maximum norm, are determined.
These pixels form one output region.  Next, the pixels thus
classified are deleted from the histogram so that they are not taken
into account for the next class.  In this modified histogram, again
the maximum is extracted; it again serves as a cluster center.  The
above steps are repeated <a href="#NumClasses"><i><code><span data-if="hdevelop" style="display:inline">NumClasses</span><span data-if="c" style="display:none">NumClasses</span><span data-if="cpp" style="display:none">NumClasses</span><span data-if="com" style="display:none">NumClasses</span><span data-if="dotnet" style="display:none">numClasses</span><span data-if="python" style="display:none">num_classes</span></code></i></a> times; thus,
<a href="#NumClasses"><i><code><span data-if="hdevelop" style="display:inline">NumClasses</span><span data-if="c" style="display:none">NumClasses</span><span data-if="cpp" style="display:none">NumClasses</span><span data-if="com" style="display:none">NumClasses</span><span data-if="dotnet" style="display:none">numClasses</span><span data-if="python" style="display:none">num_classes</span></code></i></a> output regions result.  Only pixels defined in
both images are returned.</p>
